Using mobile data

Mobile data is the way that your mobile accesses the internet when it's not connected to Wi-Fi. It will be automatically turned on when your SIM is activated. Your AGL mobile plan will include an allocation of mobile data, after which point you'll be charged for $10 for a 1GB Data Boost. If you use 3GB of Data Boosts, your data service will be barred and you'll need to call us to unbar the service. You may be charged for additional data usage ($0.01 per MB block) for a limited time before we discontinue your data access.

We'll send you data alerts when you reach 50%, 85% and 100% of your monthly data allowance. These alerts may be up to 48 hours delayed and do not include overseas calls or SMS, or usage outside Australia.

With new devices and apps coming out each day, it's common to use more mobile data than you're expecting. You can check your data usage in the AGL app. For more info, visit mobile data usage.

It's possible to turn off mobile data and still be able to receive SMS and calls, but you won't be able to use apps that require the internet, and you won’t be able to send and receive MMS.

Mobile network coverage

Our SIM plans are available using the Optus mobile network. To see full network coverage based on your address use the Coverage map.

Device compatibility

When connecting your device to an AGL mobile service, you will need to make sure your unlocked device is compatible with the Optus mobile network.

• 3G UMTS: 900 MHz
• 4G Plus: LTE 700 / 1800 / 2100 / 2300 / 2600 MHz

Multimedia Message Service (MMS) 

An MMS is a media message where the user sends any combination of text, pictures, videos or sounds to a receiver. Unlike messages in messaging apps such as WhatsApp or Messenger, MMS are sent through the mobile messaging network.

Unlimited MMS to standard Australian numbers is included in all AGL mobile plans, meaning you won't be charged any extra to send or receive them.

How to turn on MMS

When you activate a new mobile number, MMS is turned off by default.
To turn it on, please call us on 131 245.

Tethering or mobile hotspots

Tethering or hotspotting is the use of your mobile device as a way to connect to the internet. This is so that other devices like a laptop, tablet or other mobiles are able to connect to it and access the internet. AGL does not encourage tethering as this uses the mobile data allowance on your phone and can be expensive for you.

To turn on your mobile hotspot, refer to your device user manual or the manufacturers online help guides.

Calling and sending SMS to international numbers

To call an overseas number from your mobile phone, you'll need to know the country code. From your phone's keypad dial the following: [0011] [country code] [phone number].

To SMS an international number, enter the following + [country code] [phone number].

International calls may or may not be included in your AGL mobile plan, depending on the  plan you're on. For details on rates and charges, take a look at your plan's Critical Information Summary (CIS), opens in a new window and view our Mobile international call rates.

Coverage: With 3G devices, you can access the 3G (UMTS 900 MHz) network. From September 2024, Optus will be shutting down the 3G network (UMTS 900 MHz). Learn more about the 3G network closure. Before September 2024, with 4G devices and a compatible plan you can access the 3G network plus some or all of the 4G Plus network. Optus 4G Plus network uses multiple frequencies (LTE 700 /1800 / 2100 / 2300 / 2600 MHz) to provide coverage. If you bring your own device, make sure it's not locked to other networks and is compatible with the Optus network. The Optus 4G Plus network is available in all capital cities and hundreds of metro, regional and holiday towns with a compatible device and plan. Coverage and speed will vary by device and location. Check coverage on Coverage map.
